    • A variable length encoding unit includes a run-length converter, a table memory, and a variable length encoder. The run-length converter converts block data consisting of a plurality of image signals into a zero-run number and a level value in accordance with a scanning sequence. The table memory stores a VLC (variable length code) and VLC length at an address corresponding to the zero-run number and level value. The variable length encoder reads the VLC and the VLC length from the table memory in response to the zero-run number and level value converted by the run-length converter, and carries out the variable length coding by cutting the VLC from the read data in accordance with the VLC length. The variable length coding unit can flexibly handle various types of variable length coding/decoding schemes including international standard coding methods without insisting on its unique variable length coding.
    • 可变长度编码单元包括游程长度转换器,表存储器和可变长度编码器。 游程长度转换器根据扫描顺序将由多个图像信号组成的块数据转换为零运行数和电平值。 表存储器在与零运行数量和电平值相对应的地址处存储VLC(可变长度代码)和VLC长度。 可变长度编码器响应于由游程长度转换器转换的零运行数和电平值,从表存储器读取VLC和VLC长度,并且通过从读取数据中切割VLC来执行可变长度编码 符合VLC长度。 可变长度编码单元可以灵活地处理包括国际标准编码方法的各种类型的可变长度编码/解码方案,而不用坚持其唯一的可变长度编码。

    • A gear system 1 includes: an internal gear 12; an external gear 11; an input shaft 10 rotatably inserted into a center hole 11a formed in the external gear 11; and an anti-rotation section 19 configured to block rotation of the external gear 11. The input shaft 10 has an eccentric part 10a. The anti-rotation section 19 is formed such that the input shaft 10 is inserted into the anti-rotation section 19, and is rotatable about a center line of the input shaft 10. The gear system 1 includes: a brake 15 configured to disable movement of the anti-rotation section 19 about the input shaft 10; and a clutch system 16 configured to select one of a coupling state in which the anti-rotation section 19 and the input shaft 10 are coupled together to rotate together, and a non-coupling state in which the anti-rotation section 19 and the input shaft 10 are rotatable relative to each other.
